Solved! Thank you so much. I went to three electronics stores and they were all stumped!

 

[Trouble Connecting R-14 Speakers to Harmon Kardon 3490 Amp]

I could really use some help!

I previous used Tannoy powered studio monitors in my Harmon Kardon 3490 connected by XLR to Male RCA cables. I plugged them into the AUDIO Pre-Out. 

 

 

Now I'm hoping to replace them with these Klipsch R-14s, but I cannot for the life of me get the passive signal to work. I used 16-gauge wire, stripped, twisted, and connected to the twists in Speaker 1 section, but nothing. I triple checked connections and polarity, tried banana plugs and everything, but no dice. 

 

Do they need to be connected to the PRE Out with a 16 gauge open stereo wire to RCA male? Is there such a wire?

I'm so confused!
